Specification of Letters Patent.

Patented Aug. 22,1911.

Application filed October 17, 1910. Serial No. 587,463.

window-sashes being shown in closed position with the screen also inclosed or fullyrolled position and a portion of the housing for thescreen being broken away and the fully-rolled screen there shown insection; Fig. 2 is an enlarged vertical sectional View on the line 22,'Fig. 1; Fig. 3 is a detail sec tional view on the line 33, Fig. 2; andFig. 4 is a front elevational view of a window equipped with my newscreen for both sashes thereof, the said sashes being shown in partlyopen position with the screens correspondingly unwound from theirrespective rollers.

This invention relates to a certain new and useful improvement inscreens and window-frames therefor, the object of my inventian being toprovide a screen which may be removably attached to a window-sash and beraised and lowered therewith and a win- (low-frame adapted therefor.

With this object in view, my invention resides in the novelconstruction, arrangement, and combination of the several parts of myscreen and in the novel arrangement and combination of my screen with awindowframe and the sash or sashes thereof, all as will hereinafter bedescribed and afterward pointed out in the ;claim.

In the drawings, 1 indicates a windowframe of any approved constructionhaving upper and lower window-sashes 2 and 3, respecthely, slidablyarranged therein, as is usual, and a sill 4, this sill 4 being providedwith a slot, as at 5, for purposes hereinafter appearing, extendingvertically therethrough and of a length substantially equal to the widthof said sashes. sill 4, said frame 1 is provided with a housing for mynew screen, this housing comprising, or being formed by, a back portion6 and a front portion or apron 7 preferably removably secured in place,as by screws 8, for obvious reasons- Frame 1 'with said Beneath saidwindow-.

housing is adapted to be suitably arranged, as is usual, in the wall ofa building, car, or other structure, and having a sill-portion extendingforwardly on window-sill ,4. Arranged in said housing is my new screen9. This screen 9 comprises a suitable springactuated roller 10 adaptedto be rotatably mounted on suitable brackets 11 secured preferably tosaid back-portion 6 of the housing, and a roll of flexible material,wiremesh or screen, 12 secured at one end to said roller and normallywound thereon, this wire-mesh being of any suitable length asdesired andof a width substantially equal to the width of said window-sashes, sothat, when. attached to a sash, as hereinafter described, and the sashraised, it will correspondingly .cover the opening or space between thelower rail of the sash and the sill. The free end of said roll orwire-mesh 12 is adapted to be passed upwardly through said slot 5 and isprovided with what might be called a U-shaped strip 13 provided with anoutwardly-extending portion or flange 14, strip 13 being pinched orotherwise suitably secured to said free end of said wiremesh 12.

The lower rail 3 of lower window-sash 3.

is preferably cut-away or recessed, as at 16, see particularly Fig. 2,and is there provided with a plurality of screws 17 provided with broadflat heads 17*. adapted to pass through and operatively engage withsuitable slots 15 insaid strip 13, whereby, as will be seen, saidwire-mesh 12 will be removably held in engagement with said window-sash.VVhenever said sash is now raised, said wire-mesh 12 will be unwoundcorrespondingly from its said roller 10 and be held taut by the pullthereof; and when the sash is lowered, said wire-mesh 12 willautomatically, under the pull ofv its said roller, be againcorrespondingly wound thereupon, as will be clear. When said strip 13 isso attached to said sash, saidoutwardly-extending portion 14 thereof isadapted to fit snugly against should said strip 13 be disengaged fromsaid sash, said portion 14 thereof is further adapted to impinge againstsill 4 and prevent said wire-mesh 12, under the pull of its said roller,escaping back through slot 5 into said housing.

It will be noted, see particularly Fig. 2, that the height of saidcut-away portion or view.

In order to prevent the entrance of insects and the like between the twosashes of the window when the window is opened, I preferably arrange astrip of rubber or other suitable flexible material 18. on the lowerrail 2 of upper sash 2, which strip is adapted to slide or rub againstthe glass 19 of lower sash 3 when the window is opened and thus closecommunication between said sashes, as clearly shown in Figs. 1 and 2.

It is obvious that a window might readily be likewise equipped with'mynew screen for both sashes thereof, asshown in Fig. 4., if desired; andit is also to be understood that minor changes in the construct-ion,arrangement, and combination of the several parts of my screen and inthe arrangement and combination of my screen with a windowframe and thesash or sashes thereof might be made and substituted for those hereinshown and described without departing from the nature and principle ofmy invention.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

In combination, a window-frame provided with a sash slidable therein,the lower rail of said sash having a recess or cut-away portion providedwith a plurality of engaging screws,-a windowssill having a slotextending vertically therethrough, a housing beneath said sill, saidhousing comprising a said sash-recess and said screws back portion and aremovable front a ron having a sill portion extending forward y on saidwindow-sill, the upper end of said sashrecess being substantially flushwith the upper surface of said apron-sill when said sash is in closedposition, a spring actuatedroller rotatably mounted in said housingunder said window-sill, a roll of wire-mesh wound on, and secured atoneend to, said roller and having its outer or free end passing up throughsaid window-sill slot, and a substantially U-shap'ed metallic stripprovided with an outwardly-extending flange and a plurality ofslots onthe free end of said roll, said strip being adapted to fit in beingadapted to removably engage with said slots and operatively' hold saidroll in engagement with said sash against the pull of said roller,whereby, on the raising and lowering of said sash, said'roll will beunwound from and automatically rewound on said roller, and saidoutwardly-extending flange being adapted, when said screws are inengagement with said strip, to fit snugly against the under surface ofsaid lower sash-rail and, on the disengagement of said strip from saidscrews, to impinge against said window-sill and thereby prevent saidfree end .of said wire-mesh roll escaping back under the pull of saidroller through said window-sill-slot into said housing; substantially asdescribed.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses.
